Dave, I gave Tony that UM-1X. He does have one. It's been so long since I used it I don't remember enough about it to be of any help. I do know that the KN1000 does not need a USB port. You connect the midi cable end of the UM-1X to the KN1000 and the USB end to the PC.

You have a point about installing the hardware before the driver is installed. It may be necessary to delete the hardware with the PC Device Manager, install the driver, and then reinstall the hardware. BUT, I'm not sure.
